Who has last initialized the administrative tables,
who is making all the changes, and who is expected to
either commit or re-initialize (ABORT-TRANSACTION).
tmnxBfdAdminOwner is advisory only. Before beginning a transaction,
read tmnxBfdAdminOwner. If it is empty then proceed with the
configuration. Set tmnxBfdAdminOwner after setting
tmnxBfdAdminControlApply so that other users will be advised to not
make changes to the Admin tables.
Agent sets tmnxBfdAdminOwner to empty string after
tmnxBfdAdminControlApply is set - either by user initializing or
committing, or by agent timing out the uncommitted transactions
(tmnxBfdAdminLastSetTimer).
